[Python-3000] Assert syntax change...

But that's already supported...

py> assert (1+1+1+1+1+1
... +1+1+1+1+1+1+1+1+1
... >20),("The sum of many"
... "integers should be larger"
... "than a single small integer")
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AssertionError: The sum of manyintegers should be largerthan a single
small integer
